My application is running on weblogic 8.1 in linux box. Obvioiusly the classpath is pointed to the jdk which comes through the weblogic installation.
We are in a plan to migrate from weblogic to Jboss 4.0.5 (which is also works with JDK 1.4.x), want to know, do i need to use different version of JDK to run my JBoss in the same machine.
Since we don't want to disturb the application which is already running in the same machine.
You can use the same JDK to run WLS and JBoss AS.
By the way, you can install mulitiple JDKs on a single machine (I have 6) and use different ones for different purposes. Usually this involves setting the JAVA_HOME appropriately for each app. You could do this, for example, in the run script used to launch JBoss AS, and in the script used to launch WLS.
